Window Replacement & Energy-Efficient Upgrades in
Naperville, Illinois
Naperville's housing stock spans century-old homes near the Historic District to 1990s-2000s subdivision construction in areas like White Eagle and Tall Grass. Older homes commonly still carry original single-pane or early double-pane windows that have lost their seal, while builder-grade windows from the subdivision-era homes are now reaching the point where seal failure and fogging between panes become common. Renovate Right 365 is based in Naperville, so a Naperville window estimate comes from a local team, not a national call center.

What Naperville homeowners should know
Replacing windows on a Naperville home starts with Dave Sonner, the owner, coming out in person to look at each window with you. If some still have good years left, he says so. For the ones that need replacing, you get a written quote with the exact products and price, the windows are made to measure, and installation partners who have worked with Dave since the 1990s do the install. Renovate Right 365 checks whether your job needs a city permit and files it for you.

Naperville windows permit details
- WindowsConfirm with the city
- The city's permit guide lists window replacement that changes the size or style, and any new opening, as permit work. It does not say a same-size swap is exempt, so confirm your exact scope with Naperville Building Permits before work starts.
- Historic district
- In the historic district, an in-kind replacement of wood or aluminum-clad wood windows that keeps the same openings and pane divisions can get administrative review, which takes about five business days. A change in opening, style or material goes to the Historic Preservation Commission. For siding, replacing 50% or more on a primary facade is reviewed differently from smaller in-kind work, and fiber cement with a matching reveal is recognized in some wood-replacement cases. Ask the city before you pick a material.
- How to apply
- Apply through the city's Permitting, Plans and Licensing Portal. Schedule inspections at least 72 hours ahead. Questions go to 630-420-6100, option 1. Plans submitted on or after April 1, 2026 fall under the newly adopted code set, including the 2024 International Residential Code.

FAQ
Common Questions
How much does window replacement cost in Naperville?
Every home is different. After your free in-home visit and measurement, you get a clear written price based on your home's actual window count, size and condition.
Signs your window seals have failed in an Illinois winter
Fogging or condensation trapped between the panes, visible drafts near the frame even when closed, and frost forming on the inside of the glass are the most common signs a Naperville window's seal has failed and it is time for replacement.
Who files the window permit for a Naperville home?
Renovate Right 365 does. Naperville's permit guide lists window replacement that changes the size or style, and any new opening, as permit work, and applications go through the city's Permitting, Plans and Licensing Portal. Homes in the downtown historic district can need added review. We check your scope and your property's status, then file what the city requires.
Why do windows fog between the panes in older Naperville homes?
Fog trapped between the panes means the seal around the glass unit has failed, so moisture got inside and will not wipe off from either side. It is common in older Naperville homes with original or early double-pane windows, and in 1990s and 2000s builder-grade windows that are reaching that age now. Our foggy windows guide explains when a fix is enough and when replacement makes sense.
What does the written window quote include?
After Dave sees your windows in person, the quote lists the exact products and the exact price for your home, with no pressure to sign that day. It only covers the windows that actually need replacing.
Does Renovate Right 365 install both windows and siding in Naperville?
Yes. Renovate Right 365 installs both windows and insulated siding for Naperville homeowners, and one visit can cover both if you're doing both projects, so upgrades get sized together rather than sold separately.
Should I replace all my windows at once?
Not always. Dave looks at each window during the estimate and tells you which ones need replacing now and which still have good years left, so you can do the worst rooms first.
